when  the  Author,  to  the  great  !ofs

by  a  Difeafe  that  brought  him  to  his 
Death.  However  he  took  care  in 
hislaft  Will  of  its  Publication,  defi¬

But  he  was  fo  taken  up  with  Bufinefs

Holland  to  the  King  of  Great  Britain')

TO  THE

I  Doubt  not  lilt  1  (hall  incur  the  Cen¬ 
tres  of  learned  Men  for  gutting 
this  Book  into  Englilh*  becaufe 5 
thef  ll  fay 5  it  renders  Philofophy  cheap 
and  vulgar ,  and ,  which  is  worfe^fur- 
nifhes  a  fort  of  injudicious  People  with 
a  fmattering  of  Notions ,  which  Ic¬ 
ing  not  able  to  make  a  proper  ufe  of 
they  pervert  to  the  Injury  of  Religion 
and  Science .  I  confefs  the  Allegati¬ 
on  is  too  true :  but  after  Bifhop  Wil¬ 
kins,  Dr.  Burnet*  Mr.  Whifton  and 
others  y  to  fay  nothing  of  the  ancient 
Philofophers,  who  wrote  in  their  own

thors  have  treated  on  as  learned  and 
abflrufe  Subjects  in  the  fame  Language, 
1  hope  their  Example  will  he  allowed 
a  fufficient  excufe  for  printing  this 
Book  in  Englifh* 

Concerning  this  Edition  I  can  fay 5 
that  I  have  taken  care  to  have  the 
Cutts  exactly  done ,  and  have  placed 
each  Figure  at  the  Page  of  the  Book 
that  refers  to  it,  which  1  take  to  he 
more  convenient  to  the  Reader  than 
putting  them  all  at  the  End . 

I  have  keen  careful  to  procure  the

A  Man  that  is  of  Copernicus’s 
Opinion,  that  this  Earth  of

Planets  have  their  Drefs  and  Fur¬ 
niture,  and  perhaps  their  Inhabitants 
too  as  well  as*  this  Earth  of  ours: 
Efpecially  if  he  confiders  the  later 
Difcoveries  made  in  the  Heavens 
fince  Copernicus* s  time,  viz .  the 
Attendants  of  Jupiter  and  Saturn , 
and  the  champaign  and  hilly  Coun¬ 
tries  in  the  Moon,  which  are  a  ftrong 
Argument  of  a  Relation  and  Kin 
between  our  Earth  and  them,  as 
well  as  a  Proof  of  the  Truth  of  that 
Syftem.  This  has  often  been  our 
Talk,  I  remember,  good  Brother^ 
over  a  large  Telefcope,  when  We 
have  been  viewing  thofe  Bodies,  a 
Study  that  your  continual  Bufinefs 
and  Abfence  have  interrupted  for 
many  Years.  But  we  were  always 
apt  to  conclude,  that  '  twas  in  vain 
to  enquire  after  what  Nature  is  doing 
there,  feeing  there  was  no  likelihood 
of  ever  coming  to  any  Certainty  of 
the  Enquiry.  Nor  could  I  ever  find 
that  any  Philofophers,  either  antient 
or  modern,  have  attempted  any  thing 
upon  this  Subjeft.  At  the  very  Birth 

of

there  were  fome  Men  fo  bold  as  to  talk’d  of

Company  of  Worlds  in  the  Stars  .the  pU- 
But  later  Authors,  fuch  as  Cardinal^5’ hut 
Cufanus ,  Brmus,  Kfplev,  (and  if  we  farther, 
may  believe  him,  Tycho  was  of  that 
opinion  too)  have  furnifhed  the  Pla¬ 
nets  with  Inhabitants.  Nay,  Cttfa- 
nus  and  Brunus  have  allowed  the 
Sun  and  fixed  Stars  theirs  too*  But 
this  was  the  utmoft  of  their  Boldnefs  ; 
nor  has  the  ingenious  French  Author 
of  the  Dialogues  about  the  Plurality 
of  Worlds  carried  this  Matter  any 
farther.  Only  fome  of  them  have 
coined  fome  Stories  of  the  Men  in 
the  Moon,  juft  as  probable  as  Luci¬ 
an's  true  Hiftory  ;  among  which  X 
muft  count  Kypler' s,  which  he  has  di¬ 
verted  us  with  in  his  Aftronomicai 
Dream.  But  a  while  ago  thinking

not  fo  impracticable,*  nor  the 
Way  fo  ftopt  up  with  Difficulties, 
but  that  there  was  very  good  room 
left  for  probable  Conjectures.  As 
they  came  into  my  Head,  I  put  them 
down  into  common  Places,  and 
fhall  now  try  to  digeft  them  into 
fome  Method  for  your  better  Con¬ 
ception  of  them,  and  add  fomewhat 
of  the  Sun  and  fix’d  Stars,  and  the 
Extent  of  that  Univerfe  of  which 
our  Earth  is  but  an  inconfiderable 
Point.  I  know  you  have  fuch  an 
Efteern  and  Reverence  for  any  thing 
that  belongs  to  the  Heavens,  that  I 
perfwade  my  felf  you  will  read  what 
I  have  written  with  fome  Pleafure  : 
I’m  fure  I  writ  it  with  a  great  deal ; 
but  as  often  before,  fo  now,  I  find  the 
Saying  of  Jrchytas  true,  even  to  the 
Letter,  That  the?  a  Man  were  admit¬ 
ted  into  Heaven  to  view  the  wonder - 
ful  Fabrick  of  the  World ,  and  the 
Beauty  of  the  Stars$  yet  what  would

all  the  World  might  not  be  my 
Judges,  but  that  I  might  chufe  my 
Readers,  Men  like  you,  not  igno¬ 
rant  in  Aftronomy  and  true  Philofo- 
phy ;  for  with  fuch  I  might  promife 
my  felf  a  favourable  hearing,  and 
not  need  to  make  an  Apology  for  da¬ 
ring  to  vent  any  thing  new  to  the 
World,  But  becaufe  I  am  aware 
what  weak  Hands  it’s  likely  to  fall 
into,  and  what  a  fevere  Sentence  I 
may  expeQ:  from  thofe  whofe  Igno¬ 
rance  or  Zeal  is  too  great ;  it  may

There's  one  fort  who  knowing  Tk 
nothing  of  Geometry  or  Mathema-

and  ridiculous  Undertaking,  It’s 
incredible  Thing  to  them  to  talk  of 
meafuring  the  Diftance  and  Magni¬ 
tude  of  the  Stars :  And  for  the  Mo¬ 
tion  of  the  Earth,  they  count  it,  if  not 
a  falfe,  at  lea  ft  a  precarious  Opinion  ;

dation  for  the  Dreams, of  a  fanciful 
Head  and  a  diftemperM  Brain,  What 
fhould  we  anfwer  to  thefe  Men,  but 
that  their  Ignorance  is  the  Caufe  of 
their  Diflike,  and  that  if  they  had 
ftudied  thefe  things  more,  and  view¬ 
ed  the  Works  of  Nature  nicely,  they 
would  have  fewer  Scruples  ?  But  few 
People  having  had  an  opportunity  of 
profecuting  thefe  Studies,  either  fot 
want  of  Parts,  Learning  or  Leifure5 
we  cannot  blame  their  Ignorance  ; 
and  if  they  refolve  to  find  fault  with 
us  for  fpending  time  in  fuch  Matters, 
becaufe  they  do  not  underhand  the 
Ufe  of  them,  we  mull  appeal  to  pro- 
perer  Judges, 

The  other  fort,  when  they  hear  us 
talk  of  new  Lands,  and  Animals,  and 
Creatures  endued  with  as  much 
Reafon  as  themfelves,  will  be  ready 
to  cry  out,  that  we  let  up  our  Con¬ 
jectures  againfl:  the  Word  of  God, 
and  broach  Opinions  direflily  oppo- 
iite  to  Holy  Writ.  For  we  do  not 
there  read  any  thing  of  theProdu&i- 
on  of  fuch  Creatures,  no  not  fo  much 
as  that  they  exift ;  nay  rather  we 

read 


the  Planetary  Worlds.  7 

read  the  quite  contrary.  For*  ThatBookx* 
only  mentions  this  Earth  with  its  A- 
nimals  and  Plants,  and  Man  the  Lord 
of  them  :  To  fuch  Perfons  I  anfwer, 
what  has  been  often  urged  by  others 
before  me :  That  it’s  evident,  God 
had  no  defign  to  make  a  particular 
Enumeration  in  the  Holy  Scriptures, 
of  all  the  Works  of  his  Creation, 

When  therefore  it  is  plain  that  un¬ 
der  the  general  Name  of  Stars  or 
Earth  at  the  Creation,  are  compre¬ 
hended  all  the  Heavenly  Bodies,  even 
the  Attendants  upon  Jupiter  and  Sa¬ 
turn,  why  muft  all  that  Multitude 
of  Beings  which  the  Almighty  Cre¬ 
ator  has  been  plcafed  to  place  upon 
them,  be  excluded  the  Privilege,  and 
not  fuffered  to  have  a  Share  in  the 
Expreffion  ?  And  thefe  Men  them- 
felves  can’t  but  know  in  what  Senfe 
it  is  that  all  things  are  faid  to  be 
made  for  the  Ufe  of  Man,  not  cer¬ 
tainly  for  us  to  look  at  through  a 
Telefcope,  for  that’s  very  abfurd. 

Since  then  the  greateft  part  of  God’s 
Creation,  that  innumerable  multi¬ 
tude  of  Stars,  is  placed  out  of  the 

reach 


8 

Book  i®  reach  of  any  Man’s  Eye;  and  many 
them  it’s  likely,  of  the  be  ft  Glades, 
fo  that  they  don’t  feem  to  belong  to 
tis;  is  it  fuch  an  unreafonable  Opi¬ 
nion  to  think,  that  there  are  fome 
reafonable  Creatures  who  fee  and 
admire  thofe  glorious  Bodies  at  a 
nearer  diftance  ? 

Thh  En-  But  perhaps  they’ll  fay,  it  does  not 
TZttu-  become  us  to  be  fo  curious  and  inqui- 
rims *  fitive  in  thefe  Things  which  the  Su- 

preme  Creator  feerns  to  have  kept  for 
his  own  Knowledge :  For  fince  he  has 
not  been  pleafed  to  make  any  farther 
Difcovery  or  Revelation  of  them,  it 
fee  ms  little  better  than  prefumption 
to  make  any  inquiry  into  that  which 
he  has  thought  fit  to  hide.  But  thefe 
Gentlemen  muft  be  told,  that  they 
take  too  much  upon  themfelves  when 
they  pretend  to  appoint  how  far  and  ! 
no  farther  Men  fhall  go  in  their 
Searches,  and  to  let  bounds  to  other 
Menslnduftry,  as  if  they  knew  the 
Marks  that  God  has  placed  to  Know¬ 
ledge  :  or  as  if  Men  were  able  to  pafs 
thofe  Marks.  If  our  Forefathers  had 
been  at  this  rate  fcrupulous,  we  might

have  been  ignorant  ftill  of  the  Mag- Book*, 
nitude  and  Figure  of  the  Earth,  or 
that  there  was  fuch  aPlace  as  America-. 

We  fhould  not  have  known  that  the 
Moon  is  inlightned  by  the  Sun’s  Rays, 
nor  what  the  Caufes  of  the  Eclipfes 
of  each  of  them  are,  nor  a  multitude 
of  other  Things  brought  to  light  by 
the  late  Difcoveries  in  Aftronomy. 

For  what  can  a  Man  imagine  more 
abftrufe,  or  lefs  likely  to  be  known, 
than  what  is  now  as  clear  as  the  Sun? 
Whence  it  follows,  that  vigorous  In- 
duftry,  and  piercing  Wit  were  given 
Men  to  make  Advances  in  the  Search 
of  Nature,  and  there’s  no  Reafon  to 
put  any  Stop  to  fuch  Enquiries.  I 
muft  acknowledge  that  what  I  here 
intend  to  treat  of  is  not  of  that  Na¬ 
ture  as  to  admit  of  a  certain  Know¬ 
ledge  ;  I  can’t  pretend  to  affert  any 
thing  as  pofitively  true  (for  how  is  it 
poflible)  but  only  to  advance  a  pro¬ 
bable  Guefs,  the  Truth  of  which  eve¬ 
ry  one  is  at  his  own  liberty  to  exa¬ 
mine.  If  any  one  therefore  fhall

are  many  degrees  of  Probable,  feme 
nearer  Truth  than  others,  in  the  de¬

Theft  s^.ercife  of  our  Judgment.  But  befides

fo  far  are  they  from  being  of  no  ufe

this  dull  Earth,  and  viewing  it  from 
on  high,  confider  whether  Nature  has 
laid  out  all  her  Coft  and  Finery  upon 
this  fmall  Speck  of  Dirt*  So,  like

vy~ys-'  order  that  they  are  placed  round  the 
Sun,  drawn  as  near  as  can  be  in  their 
true  Proportions,  like  what  you  have 
feen  in  my  Clock  at  home.  The  fecond 
{hows  the  Proportions  of  their  Mag¬ 
nitudes  in  refpeff  of  one  another  and 
of  the  Sun,  which  you  know  is  upon 
that  fame  Clock  of  mine  too.  In  the 
firft  the  middle  Point  or  Center  is  the 
Place  of  the  Sun,  round  which,  in  an 
order  that  every  one  knows,  are  the 
Orbits  of  Mercury,  Venus,  the  Earth 
with  that  of  the  Moon  about  it ;  then 
thofe  of  Mars ,  Jupiter  and  Saturn : 
and  about  the  two  kill  the  fmall  Cir¬ 
cles  that  their  Attendants  move  in  % 
about  Jupiter  four,  and  about  Saturn 
five.  Which  Circles  as  well  as  that  of 
the  Moon  are  drawn  larger  than  their 
true  Proportion  would  admit,  other- 
wife  they  could  not  have  been  feenj 
You  may  ealily  apprehend  the  Vaft-

diftance  of  the  Earth  from  the  Sun  is 
ten  or  twelve  thoufand  of  the  Earth’s 
Diameters.  Almoll  all  thefe  Circles 
are  in  the  fame  Plane,  declining  very

little  from  that  in  which  the  Earth  Booki. 
moves,  call’d  The  Plane  of  the  Eclip - 
tick .  This  Plane  is  cut  obliquely  by 
the  Axis  upon  which  the  Earth  turns 
it  felf  round  with  refped  to  the  Sun 
in  24  Hours,  whence  arife  theSuccef 
lions  of  Day  and  Night :  The  Axis 
of  the  Earth  always  keeping  the  fame 
Inclination  to  the  Ecliptick  (except  a

nomers)  while  the  Earth  itfelf  is  car¬ 
ried  in  its  yearly  Courfe  round  the 
Sun,  caufes  the  regular  Order  of  the 
Seafons  of  the  Year:  as  you  may  fee 
in  all  Aftronomers  Books.  Out  of 
which  I  fhall  tranfcribe  hither  the 
Periods  of  the  Revolutions  of  the  Pla¬ 
nets,  viz.  Saturn  moves  round  the 
Sun  in  29  Years,  174  Days,  and  5 
1  Hours :  Jupiter  finiihes  his  Courfe  in 
1 1  Years,  317  Days,  and  15  Hours: 

Mars  his  in  about  687  Days®  Our 
Year  is  36 5  Days  6  Hours:  Venus* s

ThTpiaf  namely,  the  Diameter  of  the  Ring

Hevelius  in  the  Year  1661,  but  cal¬

If  you  would  know  the  way  that 
we  came  to  this  Knowledge  of  their 
Magnitudes,  by  knowing  the  Propor¬ 
tion  of  their  Diftances  from  the  Sun* 
and  the  Meafures  of  their  Diameters*  1 
you  may  find  it  in  the  Book  before -

the  Micrometers. 

In  this  proportion  of  the  Planets  it 
is  worth  while  to  take  notice  of  the 
prodigious  Magnitude  of  the  Sun  in 
comparifon  with  the  four  innermoft, 
which  are  far  lets  than  Jupiter  and  Sa¬ 
turn.  And  his  remarkable,  that  the 
Bodies  of  the  Planets  do  not  increafe 
together  with  their  Diilances  from 
the  Sun,  but  that  Venus  is  much  big¬ 
ger  than  Mars. 

Having  thus  explained  the  two  The  Earth 
Schemes,  there's  no  Body  I  fuppofe.^% 
but  fees,  that  in  the  firffc  the  Earth  is  IhTpiP 
made  to  he  of  the  fame  fort  with  the  nets,  and 
reft  of  the  Planets.  For  the  very  Po-^f/*’ 
fition  of  the  Circles  fhows  it.  And 
that  the  other  Planets  are  round  like 
it,  and  like  it  receive  all  the  Light 
they  have  from  the  Sun,  there’s  no 
room  (fince  theDifcoveries  made  by 
Telefcopes)  to  doubt.  Another  Thing 
they  are  like  it  in  is,  that  they  are  mo-

’tis  certain  that  Jupiter  and  Saturn 
are,  who  can  doubt  it  of  the  others  ? 
Again,  as  the  Earth  has  its  Moon  mo¬ 
ving  round  it5  fo  Jupiter  and  Saturn 
have  theirs.  Now  fince  in  fo  many 
Things  they  thus  agree,  what  can  be 
more  probable  than  that  in  others 
they  agree  too ;  and  that  the  other 
Planets  are  as  beautiful  and  as  well 
flock’d  with  Inhabitants  as  the  Earth? 
Or  what  (hadow  of  Reafon  can  there 
be  why  they  ftiould  not  ? 

If  any  one  fhould  be  at  the  Diffefti- 
on  of  a  Dog,  and  be  there  fhewn  the 
Intrails,  the  Heart,  Stomach,  Liver, 
Lungs  and  Guts,  all  the  V eins,  Arte¬

reafonably  doubt  whether  there  were 
the  fame  Contexture  and  Variety  of 
Parts  in  a  Bullock,  Hog,  or  any  other 
Beaft,tho’ he  had  never  chanc’d  to  fee 
the  like  opening  of  them  ?  I  don’t  be¬ 
lieve  he  would.  Or  were  we  tho¬ 
roughly  fatisfy’d  in  the  Nature  of  one 
of  the  Moons  round  Jupiter ,  fhould 
not  we  ftraight  conclude  the  fame  of 
the  reft  of  them  ?  So  if  we  could  be

that  is  the  Caufe  of  that  ftrange  Ap- 
pearance,  flaould  we  not  make  that  a 
Standard  to  judge  of  all  others  by  ? 

’Tis  therefore  an  Argument  of  no  Argu~ 
fmall  Weight  that  is  fetch’d  from  Re- ™mn  ,

And,  Fir  ft,  ft  is  more  than  probable  The  pla~ 
that  the  Bodies  of  the  Planets  are  fo

that  they  may  be  flock’d  with  Plants

no  Body  will  deny  but  that  there’s

Plants  and  Animals,  he’ll  find  himfelf 
non-plus’d,  and  give  you  no  likely 
account  of  their  Production.  For 
every  Thing  in  them  is  fo  exaftly 
adapted  to  fome  Defign,  every  part 
of  them  fo  fitted  to  its  proper  XJfe„ 
that  they  manifeft  an  Infinite  Wif- 
dorn,  and  exquifite  Knowledge  in 
the  Laws  of  Nature  and  Geometry, 
as,  to  omit  thofe  Wonders  in  Genera¬ 
tion,  we  fhall  by  and  by  fhow  ^  and 
make  it  an  Abfurdity  even  to  think  of 
their  being  thus  happily  jumbled  to¬ 
gether  by  a  chance  Motion  of  I  don’t 
know  what  little  Particles.  Now 
fhould  we  allow  the  Planets  nothing 
but  vaft  Deferts,  lifelefs  and  inanimate 
Stocks  and  Stones,  and  deprive  them 
of  all  thofe  Creatures  that  more  plain¬ 
ly  fpeak  their  Divine  Architect,  we 
fhould  fink  them  below  the  Earth  in 
Beauty  and  Dignity  a  Thing  very 
unreasonable,  as  I  laid  before. 

Well  then,  we  have  gain’d  the 
Point  thus  far,  and  the  Planets  may 
be  allowed  fome  Creatures  capable  of 
moving  themfelves,  not  at  all  inferior

ours,  feeing  they  have  the  fame 
Sun  to  warm  and  enliven  them  as 
ours  have, 

But  perhaps  fome  Body  may  fay, 
we  conclude  too  fait.  They  will  not 
deny  indeed  but  that  there  may  be 
Plants  and  Animals  on  the  Surface  of 
the  Planets,  that  deferve  as  well  to  be 
provided  for  by  their  Creator  as  ours 
do :  but  why  muft  they  be  of  the  fame 
Kind  with  ours :  Nature  feems  to  love 
variety  in  her  Works,  and  may  have 
made  them  widely  different  from  ours 
either  in  their  matter  or  manner  of 
Growth,  in  their  outward  Shape,  or 
their  inward  Contexture;  fhe  may 
have  made  them  fuch  as  neither  our 
Underffanding  nor  Imagination  can 
conceive.  That’s  the  Thing  we  fhall 
now  examine,  and  whether  it  be  not 
more  likely  that  fhe  has  not  obferv’d 
fuch  a  Variety  as  they  talk  of.  Nature

her  Works,  to  affe£t  V ariety,  ’tis  true ;  ^VNJ 
But  they  fhould  confider  ’tis  not  the 
Bufinefs  of  Men  to  pretend  to  fettle 
how  great  this  Difference  and  Variety 
muft  be.  Nor  does  it  follow,  becaufe 
it  may  be  Infinite,  and  out  ofour  Com- 
prehenfionand  Reach,  that  therefore 
Things  in  reality  are  fo.  Forfuppofe 
God  fhould  have  pleafed  to  have 
made  all  Things  in  the  reft  of  the 
Planets  juft  as  he  has  here,  the  Inhabi¬ 
tants  of  thofe  Places  (if  there  are  any 
fuch)  would  admire  hisWifdomand 
Contrivance  no  lefs  chan  if  they  were 
widely  different ;  feeing  they  c'an’t 
come  to  know  what’s  done  in  the 
other  Planets.  Who  doubts  but  that 
God,  if  he  had  pleafed,  might  have 
made  the  Animals  in  America  and  " 
other  diftant  Countries  nothing  like 
ours  ?  yet  we  fee  he  has  not  done  it. 

They  have  indeed  fome  difference  in 
their  Shape,  and  7tis  fit  they  fhould* 
to  diftinguifh  the  Plants  and  Animals 
of  thofe  Countries  from  ours,  who

5Tis  plain  then  that  Nature  has  not

not  allow  that  Weight  to  this  Argu¬

may  venture  to  alTert  (there  being 
fcarce  any  Doubt  of  it)  that  their 
Growth  and  Nourifhment  proceeds 
from  fome  liquid  Principle,,  For  all 
Philofophers  argee  that  there  can  be 
no  other  way  of  Nutrition;  fome  of 
the  Chief  among  them  having  made 
Water  to  be  the  Original  of  allThings : 

For  whatfoever’s  dry  and  without 
Moifture,  is  without  Motion  too  * 
and  without  Motion,  it’s  impoffible 
there  fhould  be  any  Increafe.  But  the 
Parts  of  a  Liquid  being  in  continual 
Motion  one  with  another,  and  infr* 
nuating  and  twifting  themfelves  into 
the  fmalleft  Places,  are  thereby  very* 
proper  and  apt  to  add  not  themfelves 
only,  but  whatfoever  elfe  they  may 
bring  along  with  them, to  the  Increafe 
and  Growth  of  Bodies.  Thus  we  fee 
that  by  the  Means  of  Water  the 
Plants  grow,  bloffom,  and  bear 
Fruit ;  and  by  the  Addition  of  that 
only,  Stones  grow  together  out  of

Jupiter  are  obferved  iome  Spots  of  a

Show  themfelves  to  be  Clouds:  For

Mars  too  is  found  not  to  be  without

has  been  obferved  to  turn  round  his

the  Length  of  his  Day :  but  whether  he 
has  Clouds  or  no,  we  have  not  had  the 
fame  opportunity  of  obferying  as  in 
Jupiter ,  as  well  becaufe  even  when  he 
is  neared  the  Earth,  he  appears  to  us 
much  lefs  than  Jupiter ,  as  that  his

like  fo  many  bare  Heaths,  with  no¬ 
thing  but  creeping  Shrubs  and  Bullies, 
we  may  allow  them  feme  nobler 
and  loftier  Plants,  Trees,  or  Somewhat 
like  them  :  Thefe  being  the  greateft, 
and,  except  Waters,  the  only  Ornament 
that  Nature  has  bellowed  upon  the 
Earth,  For  not  to  (peak  of  thefe  ma¬ 
ny  ufes  that  are  made  of  their  Wood, 
there’s  no  one  that  is  ignorant  either  of 
their  Beauty  or  Pleafantnefs.  Now 
what  way  can  any  one  imagine  for  a 
continual  Produ&ion  and  Succeffion  of 
thefe  Plants,  but  their  bearing  Seed  ? 

A  Method  fo  excellent,  that  it*s  the 
only  one  that  Nature  has  here  made 
ufe  of,  and  fo  wonderful,  that  it  feems 
to  be  defigned  not  for  this  Earth  alone. 

In  line,  there’s  the  fame  reafon  to  think 
that  this  Method  is  obferved  in  thofe

UU(!  °f  .  ’tis  in  Plants,  as  to  their  manner  of

Birds,  Filhes,  Worms,  Or  Infers,  uni-

ed  by  the  impregnating  of  the  Eggs, 
and  the  Copulation  of  Male  and  Fe¬

be  obferved  in  the  Planetary  Worlds? 
For  *tis  certain  that  the  Herbs  and  A-

except  the  Animals  have  Bodies  as  hard

invent  fome  new  Way  for  their  co¬

there’s  no  one  that  by  his  Duty  will  be

Book  i.  As  for  what  I  have  faid  concerning 

^/Y\J  their  Propagation,  I  cannot  be  fo  po 
fitive ;  but  the  other  Thing,  namely., 
that  they  have  Plants  and  Animals,  I 
think  I  have  fully  proved,  viz.  from 
hence,  that  otherwife  they  would  be 
inferiour  to  our  Earth.  And  by  the 
fame  Argument,  they  mu  ft  have  as 
great  a  Variety  of  both  as  we  have. 
What  this  is,  will  be  beft  known  to 
him  that  confiders  the  different  Ways 
our  Animals  make  ufe  of  in  moving 
from  one  Place  to  another.  Which  may 
be  reduc’d,  I  think,  to  thefe  ;  either 
that  they  walk  upon  two  Feet  or  Four ; 
or  like  Infers,  upon  Six5  nay  fometimes 
Hundreds ;  or  that  they  fly  in  the  Air 
bearing  up,  and  wonderfully  fleering 
themfelves  with  their  Wings;  or  creep 
upon  the  Ground  without  Feet ;  or 
by  a  violent  Spring  in  their  Bodies,  or 
paddling  with  their  Feet,  cut  them¬ 
felves  a  Way  in  the  Waters.  I  don’t 
believe,  nor  can  I  conceive,  that  there 
fhould  be  any  other  Way  than  thefe 
mentioned.  The  Animals  then  in  the 
Planets  muft  make  ufe  of  one  or  more 
of  thefe,  like  our  amphibious  Birds,

walk  on  Land,  or  fly  in  the  Air }  or 
like  our  Crocodiles  and  Sea-Horfes, 
mu  ft  be  Mongrels,  between  Land  and 
Water.  There  can  no  other  Method 
be  imagined  but  one  of  thefe.  For 
where  is  it  pofiible  for  Animals  to  live, 
except  upon  fuch  a  folid  Body  as  our 
Earth,  or  a  fluid  one  like  the  Water,  or 
Hill  a  more  fluid  one  than  that,  fuch  as 
our  Air  is?  The  Air  1  confefs  may  be 
much  thicker  and  heavier  than  ours, 
and  fo,  without  any  Difadvantage  to 
its  Tranfparency,  be  fitter  for  the  vo¬ 
latile  Animals.  There  may  alio  be  ma¬ 
ny  forts  of  Fluids  ranged  over  one  ano¬ 
ther  in  Rows  as  it  were.  The  Sea  per¬ 
haps  may  have  fuch  a  fluid  lying  on  it, 
which  tho’  ten  times  lighter  than  Wa¬ 
ter,  may  be  a  hundred  Times  heavier 
than  Air^  whofe  utmoft  Extent  may 
not  be  fo  large  as  to  cover  the  higher 
Places  of  their  Earth*  But  there’s  no 
Reafon  to  fufpeft  or  allow  them  this, 
fince  we  have  no  fuch  Thing  }  and  if 
we  did,  it  would  be  of  no  Advantage 
to  them,  for  that  the  former  Ways  of 
moving  would  not  be  hereby  at  all  in-

The  more  confiderable  Differences 
in  our  Plants  ought  to  be  thought  on, 
as  well  as  the  other.  As  in  Trees, 
that  between  the  Fir  and  the  Oak,  the 
Palm,  the  Vine,  the  Fig,  and  the  Co¬ 
co-Nut  Tree,  and  that  in  the  Indies, 
from  whofe  Boughs  new  Roots  fpring,  j 
and  grow  downwards  into  the  Earth,  jj 
In  Herbs,  the  Difference  is  notable  be¬ 
tween  Grafs,  Poppy,  Colewort,  Ivy, 
Pompions,  and  the  Indian  Fig  with 
thick  Leaves  growing  up  without  any 
Stalk,  and  Aloe.  Between  every  one 
of  which  again  there  are  many  iefs 
differing  Plants  not  taken  notice  of. 
Then  the  different  Ways  of  railing  i 
them  are  remarkable,  whether  from  1 
Seeds,  or  Kernels,  or  Roots,  or  by  ' 
grafting  or  inoculating  them.  And  I 
yet  in  all  thefe,  whether  we  confider  ‘ 
the  Things  themfelves,  or  the  Ways  of 
their  Produffion,  I  make  no  doubt  but 
that  the  Planetary  Worlds  have  as 
wonderful  a  Variety  as  we.

But  (till  the  main  and  moft  agreea-  Booki. 
ble  Point  of  the  Enquiry  is  behind, 
which  is  the  placing  forne  Spectators  An-tmais 
in  thefe  new  Difcoveries,  to  enjoy  inthePU- 
thefe  Creatures  we  have  planted  them  nets- 
with,  and  to  admire  their  Beauty  and 
Variety.  And  among  all,  that  have 
never  fo  {lightly  meddled  with  thefe 
Matters,  1  don’t  find  any  that  have 
fcrupied  to  allow  them  their  Inhabi¬ 
tants  :  not  Men  perhaps  like  ours,  but 
fome  Creatures  or  other  endued  with 
Reafon.  For  all  this  Furniture  and 
Beauty  the  Planets  are  flock’d  with 
feem  to  have  been  made  in  vain,  with¬ 
out  any  Delign  or  End,  unlefs  there 
were  feme  in  them  that  might  at  the

the  wife  Creator  of  them.  But  this 
alone  would  be  no  prevaling  Argu¬ 
ment  with  me  to  allow  them  fuch 
Creatures.  For  what  if  we  Ihouid  lay, 
that  God  made  them  for  no  other  De- 
fign,  but  that  he  himfelf  might  fee 
(not  as  we  do  ’tis  true  ^  but  that  he 
that  made  the  Eye  fees,  who  can 
doubt  ?)  and  delight  himfelf  in  the 

Contemplation  of  them?  For  was  not

account  ?  Thac  which  makes  me  of 
this  Opinion,  that  thofe  Worlds  are  not 
without  fuch  a  Creature  endued  with 
Reafon,  is,  that  otherwife  our  Earth 
would  have  too  much  the  Advantage 
of  them,  in  being  the  only  part  of  the 
Univerfe  that  could  boaft  of  fuch  a 
Creature  fo  far  above,  not  only  Plants 
and  Trees,  but  all  Animals  whatfoe- 
ver :  a  Creature  that  has  fomething 
Divine  in  him,  that  knows,  and  un- 
derftands,  and  remembers  fuch  an  in* 
numerable  number  of  Things ;  that 
deliberates,  weighs  and  judges  of  the 
Truth:  A  Creature  upon  whofe  Ac¬ 
count,  and  for  whofe  Ufe,  whatsoever 
the  Earth  brings  forth  feems  to  be  pro¬ 
vided.  For  every  Thing  here  he  con- 1 
verts  to  his  own  Ends.  With  the 
Trees,  Stones,  and  Metals,  he  builds 
himfelf  Houfes  :  the  Birds  and  Fi (lies 
he  fuftains  himfelf  with :  and  the  Wa¬ 
ter  and  Winds  he  makes  fubfervient  to 
his  Navigation  ^  as  he  doth  the  fweet 
Smell  and  glorious  Colours  of  the  Flow*  * 
ers  to  his  Delight.  What  can  there  be

in  the  Planets  that  can  make  np  for  its  Booki, 
.Defects  in  the  want  of  fo  noble  an  A-

greater  Variety  of  other  Creatures, 

I  more  Trees,  Herbs  and  Metals,  all 
thefe  would  not  advantage  or  dignify 
that  Planet  fo  much  as  that  one  Ani¬ 
mal  doth  ours  by  the  admirable  Pro¬ 
ductions  of  his  penetrating  Wit.  If  I 
-am  miitaken  in  this,  I  do  not  know 
when  to  truft  my  Reafon,  and  muffc 
allow  my  felf  to  be  but  a  poor  judge 
in  the  true  Eftimate  of  Things. 

Nor  let  any  one  fay  here,  that  there’s  vices  of 
fo  much  Villany  and  Wickednefs  in  f™d™nce

that  it’s  a  reafonable  Doubt,  whether  ™gtorthe0f

Glory  and  Ornament  of  the  Planet  they.tin~, 
that  enjoys  his  Company,  that  heJi*^- 
would  be  rather  its  Shame  and  Dif-

Men  are  tainted  with,  are  no  hin¬ 
drance,  but  that  thofe  that  follow  the 
Didates  of  true  Reafon,  and  obey  the 
Rules  of  a  rigid  Virtue,  are  ftill  a

has  the  Happinefs  to  harbour  them.

r  wonderful  Art  of  Writing,  if  its  great 
r  Ufe  and  neceffity  in  Commerce  and 
War  had  not  forced  out  the  Invention. 

'  ’Tis  to  thefe  we  owe  our  Art  of  Sail-

thofe  Difcoveries  of  which  we  are  Ma¬ 
tters  ;  and  almoft  all  the  Secrets  in 
experimental  Knowledge.  So  that 
thofe  very  Things  on  account  of  which 
the  Faculty  of  Reafon  feems  to  have 
been  accufed,  are  no  fmall  helps -to  its 
Advancement  and  Perfection.  For 
thofe  Virtues  themfelves,  Fortitude 
and  Conftancy,  would  be  of  no  ufe 
if  there  were  no  Dangers,  no  Adver- 
fity,  no  Afflictions  for  their  Exercife

If  we  fhould  therefore  imagine  in

we  confider  it  as  applied  to  Juft  ice  and 
Morality,  or  exercifed  in  the  Princi¬ 
ples  and  Foundations  of  Science.  For 
Reafon  with  us  is  that  Which  gives  us 
a  true  Senfe  of  Juftice  and  Hdnefty, 
Praife,  Kindnefs  and  Gratitude  :  ’tis 
That  that  teaches  us  to  diftinguifh  uni- 
verfally  between  Good  arid  Bad  ;  and 
renders  us  capable  of  Knowledge  and  . 
Experience  in  it.  And  can  there  be  : 
i  any  where  any  other  Sort  of  Reafon  ! 
than  this  ?  or  can  what  We  call  juft  J

at  all,  I  don’t  fay  probable,  but  pofft-  I

neither  will  Life  be  any  Pleafure  to

I  think  it  very  probable,  that  all  their

poffiblefor  Animals  to  provide  Food  for 
themfelves,  or  be  fore-warn’d  of  any 
approaching  Danger,  fo  as  to  guard 
themfelves  from  it.  So  that  where-ever 
we  plant  any  Animals,  except  we  wou’d 
have  them  lead  the  Life  of  Worms  or 
Moles, we  muft  allow  them  Sight:,  than 
which  nothing  can  conduce  more  ei¬

the  prefervation  and  continuance  of

nefs  and  Prefervation  it’s  very  proba¬ 
ble  the  reft  of  the  Planets  are  not  with¬ 
out  it.  Certainly  when  I  confider  all 
thefe  Things,  how  great,  noble,  and 
ufeful  they  are  when  I  confider  what 
an  admirable  Providence  it  is  that 
there’s  fuch  a  Thing  as  Pleafure  in

Earth,  the  fmalleft  part  almoft  of  the 
Univerfe,  was  never  defign’d  to  mo¬ 
nopolize  fo  great  a  Blefling.  And  thus 
much  for  thofe  Pleafures  which  afteft 
our  bodily  Senfes,  but  have  little  or  no

1  have  already  made  not  unlikely*  Let 
us  now  fee  whether  they  may  not  have 
Fire  alfo :  which  is  not  fo  properly 
call’d  an  Element,  as  a  very  quick 
Motion  of  the  Particles  in  the  inflama- 
ble  Body.  But  be  it  what  it  will, 
there  are  many  Arguments  for  their 
not  being  without  it.  For  this  Earth 
is  not  fo  truly  call’d  the  Place  of  Fire 
as  the  Sun  :  and  as  by  the  Heat  of  that 
all  Plants  and  Animals  here  thrive  and 
live ;  fo,  no  doubt,  it  is  in  the  other 
Planets.  Since  then  Fire  is  caufed  by 
a  moft  intenfe  and  vigorous  Heat,  it 
follows  that  the  Planets,  efpecially 
thole  nearer  the  Fountain  of  it,  have 
their  proportionate  degrees  of  Heat 
and  Fire.  And  fince  there  are  fo  ma¬ 
ny  ways  of  its  Production,  as  by  the 
collection  of  the  Rays  of  the  Sun,  by 
the  reflection  of  Mirrors,  by  the  lin¬

it’s  ftrange  if  neither  Art  fhould  have

there  by  one  of  thefe  many  means. 

Then  how  ufeful  and  neceifary  is  it  to 
us  ?  By  it  we  drive  away  Cold,  and 
fupply  the  want  of  the  Sun  in  thofe 
Countries  where  his  oblique  Rays 
make  a  lefs  vigorous  Impreffion,  and 
fo  keep  a  great  part  of  the  Earth  from 
being  an  uninhabited  Defart :  which 
is  equally  neceffary  in  all  the  Planets, 
whether  we  allow  them  Succeffion  of 
i  Seafons,  ora  perpetual  Spring  and  cE~ 
quinox  :  for  even  then  the  Countries 
near  the  Pole  would  receive  but  little 
Advantage  from  the  Heat  of  the  Sun, 

By  the  help  of  this  we  turn  the  Night 
into  Day,  and  thereby  make  a  confi- 
derable  addition  to  the  fhortnefs  of 
our  Lives.  Upon  all  thefe  Accounts 
we  ought  not  to  think  this  Earth  of

the  other  Planets  from  fo  advantage¬ 
ous  and  fo  profitable  a  Gift.

They  do  not  only  view  the  Stars,  but

ConjeBures  concerning 

This  Suppofition  of  their  Knowledge 
and  Ufe  of  Aftronomy  in  the  Planeta¬ 
ry  Worlds,  will  afford  us  many  new 
Conjeftures  about  their  manner  of 
Life,  and  their  State  as  to  other  things. 

For,  Firft  :  No  Obfervations  of  the 
Stars  that  are  neceffary  to  the  Know¬ 
ledge  of  their  Motions,  can  be  made 
without  Inftruments ;  nor  can  thefe 
be  made  without  Metal,  Wood,  or 
fame  fuch  folid  Body.  Here’s  a  ne- 
ceflity  of  allowing  them  the  Carpen¬ 
ters  Tools,  the  Saw,  the  Ax,  the 
Plane,  the  Mallet,  the  File  :  and  the 
making  of  thefe  requires  the  Ufe  of 
Iron,  or  fome  equally  hard  Metah 
Again,  thefe  Inftruments  can’t  be  with¬ 
out  a  Circle  divided  into  equal  Parts, 
or  a  ftrait  Line  into  unequal.  Here’s 
a  neceffity  for  introducing  Geometry 
and  Arithmetick.  Then  the  Necef¬ 
fity  in  fuch  Obfervations  of  marking 
down  the  Epochas  or  Accounts  of 
Time,  and  of  tranfmitting  them  to 
Pofterity,  will  force  us  to  grant  them 
the  Art  of  Writing;  perhaps  very  dif¬ 
ferent  from  ours  which  is  commonly 
ufed,  but  I  dare  affirm  not  more  inge¬ 
nious*

nious  or  eafy.  For  how  much  more  Booki, 
ready  and  expeditious  is  our  Way,  than 
by  that  multitude  of  Characters  ufed 
inChina  j  and  how  vaftly  preferable  to 
Knots  tied  in  Cords,  or  the  Pictures 
in  ufe  among  the  barbarous  People  of 
Mexico  and  Peru  ?  There’s  no  Nation 
in  the  World  but  has  fame  way  or 
other  of  writing  or  marking  down 
their  Thoughts :  So  that  it’s  no  won¬ 
der  if  the  Planetary  Inhabitants  have 
been  taught  it  by  that  great  Schooi- 
\  miftrefs  Neceflity,  and  apply  it  to  the 
Study  of  Aftronomy  and  other  Scien¬ 
ces.  fn  Aftronomical  Matters  the  Ne¬ 
ceflity  of  it  is  moreover  apparent  from 
hence,  that  the  Motion  of  the  Stars  is 
as  hwere  to  be  fancied  and  guefs’d  at 
in  different  Syftems,  and  thefe  Syftems 
to  be  continually  improved  and  cor¬ 
rected,  as  later  and  more  exaCt  Obfer-

fo  certain  a  Knowledge  of  the  true

we  have  fo  admirable  an  Invention 
of  Telefcopes  to  help  our  failing  Eye-

different  Forms  of  the  Planetary  Bo¬

Surface  of  the  Moon,  in  the  bringing 
to  light  an  innumerable  multitude  of 
Stars  otherwife  invifible,  that  we  rauft 
neceffarily  be  far  their  Matters  in  that 
Knowledge.  Hence  it  is  almoft  necef- 
fary  (except  we  have  a  Mind  to  flat¬ 
ter  and  complement  our  felves  as  the 
only  People  that  have  the  Advantage 
of  fuch  excellent  Inventions)  either  to 
allow  the  Planetary  Inhabitants  fuch 
fharp  Eyes  as  not  to  need  them,  or 
elfe  the  ufeofGlaffes  to  help  the  Defi¬

Ians.  For  if  one  confiders  the  Ignorance 
of  thofe  Nations,  and  of  others  in  Afia 
and  Africa  equally  barbarous,  it  will 
appear  as  if  the  main  Defign  of  the 
Creator  in  placing  Men  upon  the  Earth 
r  was  that  they  might  live,  and,  in  a 

!juft  fenfe  of  all  the  Blellings  and  Plea-

;  few  went  beyond  the  Bounds  of  Na¬ 
ture  in  their  Enquiries  after  Know¬ 
ledge,  There  does  not  want  an  Am 
fwer  to  thefe  Men.  For  God  could 
not  but  forefee  the  Advances  Men 
would  make,  in  their  enquiring  into 
the  Heavenly  Bodies :  that  they  would 
difcover  Arts  ufeful  and  advantageous 
to  Life  :  that  they  would  crofs  the  Seas* 
and  dig  up  the  Bowels  of  the  Earth, 
Nothing  of  all  this  could  happen  contra¬ 
ry  to  the  Mind  and  Knowledge  of  the 
Infinite  Author  of  all  Things.  And  if 


68 

Booki.he  forefaw  thefe  Things  would  be9 
he  fo  appointed  and  cleitin’d  them  to 
humane  kind.  And  the  Studies  of  Arts 
and  Sciences  cannot  be  fa  id  to  be  con¬ 
trary  to  Nature,  frnce  in  the  feareh 
thereof  they  are  employ’d  :  efpecially  if 
we  confider  how  great  the  natural  de¬ 
fire  and  love  of  Knowledge,  rooted  in 
all  Men  is.  For  its  impartible  this 
fhould  have  been  given  them  upon  no 
Defign  or  Account.  Bul  they  will 
urge,  that  if  fuch  a  Knowledge  is 
natural,  if  we  were  born  for  it,  why 
are  there  fo  very  few,  efpecially  in 
Aftronomy,  that  profecute  thefe  Stu¬ 
dies  ?  For  Europe  is  the  only  Quarter 
of  the  Earth  in  which  there  have 
been  any  Advancements  made  in  A- 
ftronomy.  And  as  for  the  Judicial  A- 
ftrology,  which  pretends  to  foretel 
what  is  to  come,  it  is  fuch  a  wretched 
and  oftentimes  mifehievous  piece  of 
Madnefs,  that  Ido  not  think  it  ought 
to  be  fo  much  as  named  here.  And 
even  in  Europe,  not  one  in  a  hundred 
Thoufand  meddles  with  thefe  Studies. 
Befides,  its  Original  and  Rife  is  fo

the  very  firft  Rudiments  of  Aftronomy  Booki* 
or  Geometry  (which  is  neceffary  to  the  ^ v ~ 
learning  of  it)  were  known.  For  eve- 
ry  Body  is  acquainted  aimoft  with  its 
firft  Beginnings  in  Egypt  and  Greece . 

Add  to  this,  that  his  not  yet  above 
fourfcore  Years  frnce  the  bungling  E- 
picycles  were  difcarded,  and  the  true 
and  eafy  plain  Motion  of  the  Planets 
was  difcovered.  For  the  Satisfaction 
of  thefe  Scruples,  to  what  we  faid 
before,concerning  the  Fore-knowledge 
of  God,  may  be  added  this ;  That  God 
never  defigned  we  fhould  come  into 
the  World  Aftronomers  or  Philofo- 
phers  thefe  Arts  are  not  infufed 
into  us  at  our  Birth,  but  were  or¬ 
dered,  in  long  Trafts  of  Time,  by 
degrees  to  be  the  Rewards  and  Re- 
fult  of  laborious  Diligence  ;  efpecial- 
ly  thofe  Sciences  which  are  now  in 
debate,  are  fo  much  the  more  difficult 
and  abftrufe,  that  their  late  Invention 
and  flow  Progrefs  are  fo  far  from  being 
a  Wonder,  that  it  is  rather  ftrange 
they  were  ever  difcover’d  at  all.  There 
are  but  few,  I  acknowledge  one  or  two 
perhaps  in  an  Age,  that  purfue  them,

Number  will  be  very  confiderable  if  we 
take  in  tnofe  that  have  lived  in  all  the 
Ages  in  which  Aftronomy  hath  flou¬ 
rished  :  and  no  Body  can  deny  them 
thatHappinefs  andContentment  which 
they  have  pretended  to  above  all  others. 
In  fine,  it  was  fufficient  that  fo  fmall 
a  Number  fliould  make  it  their  Study* 
fo  that  the  Profit  and.  Advantage  of 
their  Inventions  might  but  fpread  it 
felf  over  all  the  World.  Since  then 
the  Inhabitants  of  this  Earth,  let  them 
be  never  fo  few,  have  had  Parts  and 
Genius  fufficient  for  the  Attainment  of 
this  Knowledge;  and  there’s  no  reafon 
to  think  the  Planetary  Inhabitants  lefs 
ingenious  or  happy  than  our  felves ;  we 
have  gain’d  our  Point,  and  ;tis  probable 
that  they  are  as  skilful  Aftronomers  as 
we  can  pretend  to  be.  So  that  now 
we  may  venture  to  deduce  feme  Con' 
fequences  from  fuch  a  Supposition. 

We  have  before  fhow’d  the  neceffa- 
ry  Dependence  and  Connexion,  not 
only  of  Geometry  and  Arithmetick, 
but  of  Mechanical  Arts  and  In fl: ru¬ 
men  ts  with  this  Science.  This  leads 

us

us  naturally  to  the  Enquiry  how  they  Book  1. 
j  can  ufe  thefe  Inftruments  and  Engines 
for  the  Obfervation  of  the  Stars,  how 
they  can  write  down  fuch  their  Obfer-

which  we  do  with  our  Hands.  So 
that  we  muft  neceffarily  give  them 
!  Hands,  or  fome  other  Member,  as  con-  Tfoy  havt 
venient  for  all  thofe  Ufes,  inftead  0[Han 
them.  One  of  the  ancient  Philofophers 
laid  fuch  Strefs  upon  the  Ufe  and  Con- 
veniency  of  the  Hands,  that  he  made 
no  fcruple  to  affirm,  they  were  the 
Caufe  and  foundation  of  all  our 
Knowledge.  By  which,  I  fuppofe,  he 
meant  no  more,  than  that  without  their 
Help  and  Affiftance  Men  could  never 
arrive  to  the  Improvement  of  their 
Minds  in  natural  Knowledge :  And 
indeed  not  without  Reafon.  For  fup¬ 
pofe  inftead  of  them  they  had  had 
Hoofs  like  Horfes  or  Bullocks  given 
them,  they  might  have  laid  indeed  the 
Model  and  DelignofCitiesand  Houfes

we  invent  or  imagine  that  could  be  fo 
exaftly  accommodated  to  all  the  de- 
fign’d  U fes  as  the  Hands  are  ?  Elephants 
can  lay  hold  of,  or  throw  any  thing 
with  their  Probofcis,  can  take  up  even 
the  fmalleft  Things  from  the  Ground' 
and  can  perform  fuch  furprifing  Things 
with  it,  that  it  has  not  very  improper¬

don’t  know  w  hat  Effect  this  Argument, 
from  the  immutable  Nature  of  thefe

Strength  as  that  which  I  made  uie  of 
above  to  prove  that  the  Planetary  In¬

But  if  they  take  delight  in  Harmo¬ 
ny,  there  is  no  doubt  but  that  they 
have  invented  Mufical  Inftruments. 

For  they  could  fcarce  help  lighting

from  all  thefe,  and  yet  be  very  good* 
But  why  we  fhould  look  upon  their

no  reafon  can  be  given  ;  neither  can 
we  well  prefume  that  they  want  the

feeing  the  Invention  of  Half  Notes  is  fo

an  Inhabitant  of  Jupiter  or  Venus  will 
perhaps  give  you  a  better  Reafon  for

Booki.as  tovary  from  their  ufual  Proports- 
v<v^  ons,  and  thereby  to  bear  a  little  this 
way  or  that,  in  order  to  regulate  the 
Scale.  And  why  this  Temperature  is 
beft  in  the  Sy  ftem  of  the  Strings,  when 
out  of  the  Fifth  the  fourth  Part  of  a 
Comma  is  ufually  cut  off  ^  This  fame 
thing  I  have  formerly  fhe  w’d  at  large. 

But  tor  the  regulating  the  Tone  of 
the  Voice  (as  I  before  hinted)  that  may 
admit  of  a  more  eafy  proof,  and  we  fhall 
give  you  an  Effay  of  it,  fince  I  have 
mentioned  a  thing  that  is  not  mere  I- 
magination  only :  I  fay  therefore,  if 
any  Perfon  ftrike  thofe  Sounds  which 
the  Muficiansdiftinguifh  by  thefe  Let¬ 
ters,  C,  F,  D,G,C,  by  thefe  agreeable 
Intervals,  altogether  perfed,  inter¬ 
changeable,  afcending  and  descending 
with  the  Voice :  Now  this  latter  found 
C  will  be  one  Comma,  or  very  fmall  j 
portion  lower  than  the  firft  founding  of 
C.  Becaufe  of  thefe  perfed  Intervals, 
which  are  as  4  to  3,  $  to  6,  4  to  3, 

2  to  3,  an  account  is  made  in  fuch  a 
Proportion,  as  160  to  162.  that  is,  as 
80  to  81,  which  is  what  they  call  a 
Comma.  So  that  if  the  fame  Sound 

fliould

filould  be  repeated  nine  times,  theBooki* 
Voice  would  fall  near  the  Matter  a 
greater  Tone,  whofe  proportion  is  as 
8  to  9.  But  this  the  Senfeof  the  Ears 
by  no  means  endures,  but  remembers 
the  firft  Tone,  and  returns  to  it  again. 
Therefore  we  are  compelfd  to  ule  an 
i  occult  Temperament,  and  to  fmg  thefe 
t  imperfeft  Intervals,  from  doing  which 
I  lefs  Offence  arifes.  And  for  the  moft 
[  part,  all  Singing  wants  this  Tempera- 
;  ment,  as  may  be  collefted  by  the  afore* 

!:  faid  Computations.  And  thefe  things 
we  have  offer’d  to  thofe  that  have 
iome  Knowledge  in  Geometry. 

We  have  (poke  of  thefe  Arts  and 
Inventions,  which  it  is  very  probable 
1  the  Inhabitants  of  the  Planets  partake 
of  in  common  with  us,  befides  which 
it  feems  requifite  to  take  in  many  other 
Things  that  ferve  either  for  the  Ufe  or 
Pleafure  of  their  Lives.  But  what 
thefe  Things  are  we  fhall  the  better  ac¬ 
count  for,  by  laying  before  us  many  of 
thofe  Things  which  are  found  among 
us.  I  have  before  mention’d  the  Varie¬ 
ty  of  Animals  and  Vegetables,  which 
very  much  differ  from  each  other, 

G  among;

fer  but  little  ;  and  I  have  faid,  that 
there  are  no  lefs  differences  in  thefe 
Things  in  the  Planetary  Worlds. 

I  ihall  now  take  a  fhort  view  of  the 
Benefits  we  receive  both  from  thofe 
Herbs  and  Animals,  and  fee  whether 
we  may  not  with  very  good  reafon  con¬ 
clude  that  the  Planetary  Inhabitants 
reap  as  great  and  as  many  from  thofe 
that  their  Countries  afford  them. 

And  here  it  may  be  worth  our  while 
to  take  a  Review  of  the  Variety  and 
Multitude  of  our  Riches.  For  Trees  i 
and  Herbs  do  not  only  ferve  us  for 
Food,  they  in  their  delicious  Fruits, 
thefe  in  their  Seeds,  Leaves  and  Roots  • 
but  Herbs  moreover  furnifh  us  with 
Phy fick,  and  Trees  with  Timber  for 
our  Houfes  and  Ships.  Flax,  by  the 
means  of  thofe  two  ufeful  Arts  of  \ 
Spinning  and  Weaving,  affords  us  ! 
Clothing.  Of  Hemp  or  Matweed  ;l 
we  twift  our  felves  Thread  and  fmall  j 
Ropes,  the  former  of  which  we  em¬ 
ploy  in  Sails  and  Nets,  the  latter  in 
making  larger  Ropes  for  Mails  and  l 
Anchors.  With  the  fweet  Smells  and  1

that  offend  our  Noftrils,  or  are  mif-  vantages 
chievous  to  our  Bodies,  are  feldom reaP  . 
without  excellent  Ufes :  or  were  mad Q^ndAnP 
perhaps  by  Nature  as  a  Foil  to  fet  off, 
and  make  us  the  more  value  the  Good 
by  comparing  them  with  thefe.  What  k 
vaft  Advantages  and  Profit  do  we  reap 
from  the  Animals?  The  Sheep  give  us 
Clothing,  and  the  Cows  afford  us 
Milk:  and  both  of  them  their  FJeih 
for  our  Suftenance.  '  Affes,  Camels, 
and  Horfes  do,  what  if  we  wanted 
them  we  muff  do  our  felves,  carry 
our  Burdens ;  and  the  laft  of  them  we 
make  ufe  of,  either  themfelves  to  car¬ 
ry  us,  or  in  our  Coaches  to  draw  us* 

In  which  we  have  lb  excellent,  fo  ufe- 
ful  an  Invention  of  Wheels,  that  I 
can’t  fuppofe  the  Planets  to  enjoy  Soci¬ 
ety  and  all  its  Confequences,  and  be 
without  them.  Whether  they  are  Py¬ 
thagoreans  there,  or  feed  upon  Fleffi 
as  we  do,  I  dare  not  affirm  any  Thing*

But  it  is  a  furprifing  thing!  that  a  ra¬ 
tional  Creature  Ihould  live  upon  the 
Ruin  and  Deftruftion  of  fuch  a  num¬ 
ber  of  other  his  Fellow-Creatures !  And 
yet  it  does  not  feem  at  all  unnatural, 
fince  not  only  he,  but  even  Lions, 
Wolves,  and  other  ravenous  Beafts, 
prey  upon  Flocks  of  other  harmlefs 
Things,  and  make  mere  Fodder  of 
them  \  as  Eagles  do  of  Pidgeons  and 
Hares  ;  and  large  Filh  of  the  helplefs 
little  ones.  We  have  different  forts  of 
Dogs  for  Hunting,  and  what  our  own 
Legs  cannot,  that  their  Nofe  and  Legs 
can  help  us  to.  But  the  Ufe  and  Pro¬ 
fit  of  Herbs  and  Animals  are  not  the 
only  Things  they  are  good  for,  but  they 
raife  our  Delight  and  Admiration  when 
we  confider  their  various  Forms  and 
Natures,  and  enquire  into  all  their  dif¬ 
ferent  ways  of  Generation  :  Things  fo 
infinitely  multifarious,  and  fo  delight¬ 
fully  amazing,  that  the  Books  of  na¬ 
tural  Philofophers  are  defervedly  filled 
with  theirEncomiums.  For  even  in  the

very  Infers,  who  can  but  admire  the  Books, 
fix-corner’d  Cells  of  the  Bees,  or  the

Bag  of  a  Silk-  worm,  which  laft  affords 
us,  with  the  Help  of  incredible  Indu- 
ftry,  even  Shiploads  of  foft  delicate 
Clothing.  This  is  a  fhort  Summary 
of  tbofe  many  profitable  Advantages 
the  animal  and  herbal  World  ferve 
us  with. 

But  this  is  not  all*  The  Bowels  of

Cunning  does  he  employ  in  finding,  in 
digging,  in  trying  Metals,  and  in 
melting,  refining,  and  tempering  them  ?

drawing  or  diffolving  Gold,  fo  as  with Metals% 
inconfiderabie  Changes  to  make  every 
Thing  he  pleafes  put  on  that  noble

Ufes  is  iron?  and  how  ignorant  in  all 
Mechanical  Knowledge  were  thofe 
Nations  that  were  not  acquainted  with

There’s  one  Thing  indeed  we  have, 
which  it’s  a  Queftion  whether  it  has

Book  f.  done  more  harm  or  good,  and  that  is 
Gun-powder  made  of  Nitre  and  Brim-

we  had  got  a  more  fecure  Defenfe  than 
former  Ages  againft  ail  Ailaults,  and 
could  eafily  guard  our  Towns,  by  the 
wonderful  Strength  of  that  Invention,

we  find  it  has  rather  encouraged  them, 
and  at  the  fame  time  been  no  fmail  Qc-

is  of  fufficient  Proof :  but  which  lays 
every  Thing,  Caftles  and  Towers,  be 
they  never  fo  ftrong,  even  with  the 
Ground.  If  for  nothing  elfe,  yet  up¬ 
on  this  one  account,  I  think  we  had 
better  have  been  without  the  Difco ve¬ 
ry.  Yet,  when  we  were  talking  of 
our  Difcoveries,  it  was  not  to  be 
pafs’d  over,  for  the  Planets  too  may 
have  their  mifchievous  as  well  as  ufe-

fo  many  different  Employments,  For 
with  them  we  grind  our  Corn,  and 
fqueeze  out  our  Oil;  with  them  we

them  we  beat  our  Stuff  for  Paper.  An 
incomparable  Invention !  Where  the

To  thefe  we  may  add  the  late  difcove- 
ry  of  Printing,  which  not  only  pre- 
ferves  from  Death  Arts  and  Know¬ 
ledge,  but  makes  them  much  eafier  to 
be  attained  than  before.  Nor  mu  ft

on  his  Journey,  he  lays  down  thefe  two 
Things  as  certain  j  that  no  Motion, 
muft  be  allowed  the  Earth,  and  that: 
God  has  made  nothing  in  the  Planets, 
no  not  fo  much  as  Herbs,  which  has 
either  Life  or  Senfe  in  it.  Leaving 
then  the  Syftem  of  Copernicus,  he  chu-  -

lie  iuppofes  all  the  fix’d  Stars  to  be  i

their  Planets,  here  (againft  his  Will  I

finite  number  of  Copernican  Syftems. 
All  which,  befide  their  own  Motion, 
he  abfurdly  makes  to  be  carried,  with 
an  incredible  fwiftnefs,  in  twenty  four

thing  but  infernal,  flunking,  blacki 
Flames  and  Smoke  :  and  Saturn  was  all  . 
melancholy,  dreadful,  nafty ,  and  dark : 
for  thefe  are  the  Planets  (I  don’t  know 
why,  but  all  Fortune-tellers  hate  them} 
that  bring  all  the  Plagues  and  Mifchiefssli

nough  of  this  j  let’s  have  have  done 
with  this  famous  Author :  And  now 
that  we  have  ventur’d  to  place  Specta¬ 
tors  in  the  Planets,  let  us  examine  each 
of  them,  and  fee  what  their  Years, 
Days,  and  Aftronomy  are. 

TheSyftem  To  begin  with  the  innermoft  and 

6lauil<l~  neareft  the  Sun  :  We  know  that  Mer- 

Mercury.  cury  is  three  times  nearer  that  vaft  Bo¬ 
dy  of  Light  than  we  are.  Whence  it 
follows  that  they  fee  him  three  times 
bigger,  and  feel  him  nine  times  hotter 
than  we  do.  Such  a  degree  of  Heat 
would  be  intolerable  to  us,  and  fet  a- 
fire  all  our  dry’d  Herbs,  our  Hay  and 
Straw  that  we  ufe.  And  yet  there  is 
no  doubt  but  that  the  Animals  there, 
are  made  of  fuch  a  Temper,  as  to  be 
but  moderately  warm,  and  the  Plants 
fuch  as  to  be  able  to  endure  the  Heat. 
The  Inhabitants  of  Mercury ,  it’s  likely, 
have  the  fame  opinion  of  us  that  we 
have  of  Saturn ,  that  we  mull  be  intol- 
lerably  cold,  and  have  little  or  no  Light, 
we  are  fo  far  from  the  Sun.  There’s  rea- 
fon  to  doubt,  whether  the  Inhabitants 
of  Mercury,  tho’  they  live  fo  much  near¬ 
er

them  by  what  we  fee  here,  we  {hall 
not  be  obliged  to  grant  it  The  Inha¬ 
bitants  of  Africa  and  Brafil ,  that  have 
got  for  their  Share  the  hotteft  Places 
in  the  Earth,  being  neither  fo  wife  nor 
lb  induftrious  as  thofe  chat  belong  to 
colder  and  more  temperate  Climates  j 
they  have  fcarce  any  Arts  orKnowledge 
among  them ;  and  thofe  of  them  that 
live  upon  the  very  Shore,  understand 
little  or  no  Navigation.  Nor  can  I  be 
willing  to  make  all  that  vaft  number 
that  mud  inhabit  thofe  two  large  Pla¬ 
nets,  Jupiter  and  Saturn^ and  have  luch 
noble  Attendance,  mere  dull  Block¬ 
heads,  or  without  as  much  Wit  as  our 
Selves,  tho’  they  are  fofar  more  diftant 
from  the  Sun.  The  Aftronomy  of  thofe 
that  live  in  Mercury ,  and  the  appear¬ 
ance  of  the  Planets  to  them,  oppofite 
at  certain  times  to  the  Sun,  may  be 
eafily  conceived  by  the  Scheme  of  the 
Cofern ican  Syftem  in  the  former 
Part.  At  the  times  of  thefe  Oppofiti- 
ons  Venus  and  the  Earth  rauft  needs

reafon  to  doubt  but  that  he  has  his 1 
Days  and  Nights  as  well  as  they.  But 
his  Year  is  fcarce  the  fourth  part  fo >;

The  Inhabitants  of  Venus  have  much

The  Sun  appears  to  them  larger  by

of  this  equal  appearance  ;  but  when  I 
ufed  an  Eye-glafs  that  wasfmok’d  for

What  then,  has  Venus  no  Sea,  or  do  the 
Waters  there  refletf  the  Light  more 
than  ours  do,  or  their  Land  lefs  ?  Or 
rather  (which  is  mod  probable  in  my 
Opinion)  is  not  all  that  Light  we  fee 
reflected  from  an  Atmofphere  fur¬ 
rounding  Venus,  which  being  thicker 
and  more  folid  than  that  in  Mars  or 
Jupiter,  hinders  our  feeing  any  thing 
of  the  Globe  it  felf,  and  is  at  the  fame  r 
time  capable  of  fending  back  the  Rays 
that  it  receives  from  the  Sun  }  For  it 
is  certain  that  if  we  looked  on  the 
Earth  from  the  outfide  of  the  At¬ 
mofphere,  we  fhould  not  perceive 
fuch  a  difference  as  we  do  from  a

Winter,  the  Axis  of  that  Planet  having

UYV  believe,  that  the  Land  in  Mars  is  of  a 
blacker  Colour  than  that  of  Jupiter  or 
the  Moon,  which  is  the  reafon  of  his 
appearing  of  a  Copper  Colour,  and  his 
reflecting  a  weaker  Light  than  is  pro¬ 
portionable  to  his  distance  from  the

Venus.  Nor  has  he  any  Moon  to  wait 
upon  him,  and  in  that,  as  well  as  Mer¬

are  One  or  Two  more  ftill  behind,  and 
not  without  reafon.  For  between  the

at  all  proportionable  to  that  between

there  may  be  a  Sixth;  or  perhaps  there

of  his  Orbit,  which  is  towards  the

very  good  reafon. 

Perhaps  when  Saturn  comes  into

ly  they  have  but  the  five  and  twen*

we  receive  from  it.  But  that  Light 
is  not  fo  weak  as  we  imagine,  as  is

us,  as  that  only  the  25th  part  of  his 
Disk  remains  uncovered,  he  is  not 
fenfibly  darken’d.  But  if  you  have  a 
mind  exa£Hy  to  know  the  Quantity  of 
Light  that  Jupiter  enjoys, you  may  take 
a  Tube  of  what  Length  you  pleafe.  Let 
one  end  of  it  be  clofed  \yith  a  Plate  of

In  the  Morning  it  difappears,  leaving 
behind  it  a  Likenefs  indeed  of  a  Bow, 
but  much  paler  and  weaker  than  our 
Moon  is  in  the  Day  time.  For  they, 
as  I  faid  before,  have  an  Atmofphere, 
or  an  Air  lurrounding  them  enlighten’d 
by  the  Sun.  Otherwife  Night  and 
Day  they  would  have  their  Ring, 
their  Moons,  and  all  the  fix’d  Stars, 
equally  confpicuous.  Another  thing 
that  muft  make  the  Sight  of  their  Ring 
very  curious,  is,  that  by  fome  Spots  in 
It,  it  is  difcover’d  to  turn  round  upon 
it  felf:  A  thing  that  thofe  that  are  fo 
near  cannot  but  take  notice  ofj  when

a  great  Inequality,  the  infide  of  it  be¬

both  of  the  Sun  and  Ring  for  a  confi-  Books, 
derable  time,  the  latter  of  which  hides 
fome  part  of  the  Stars  from  it  too.  And 
certainly  an  amazing  Thing  it  mu  ft 
be,  all  of  a  fudden  to  have  the  Sun  in¬ 
tercepted  and  to  become  as  dark  as 
Midnidght,  without  feeing  any  Caufe 
of  fuch  an  Accident.  All  which 
time  their  Moons  are  their  only  Com¬ 
fort.  The  other  half  of  the  Year 
the  Hemifphere  T  B  V  enjoys  the 
fame  Light  that  T  A  U  before  did, 
and  then  this  undergoes  thofe  long  E- 
clipfes  that  That  before  fuffer’d.  At 
the  Equinoxes,  when  the  Sun  is  in  the 
fame  Plane  with  the  Ring,  the  Inhabi¬ 
tants  of Saturn  cannot  well  perceive  it: 
no  not  even  we  with  our  Glades,  by 
reafon  of  its  Darknefs.  This  happens 
when  Saturn ,  view’d  from  the  Sun,  is 
advanced  one  and  twenty  degrees  and 
a  half  in  Virgo  or  Pifces ,  as  I  have 
fhow’d  formerly  in  my  Syftem  of  Sa¬

Conjectures  concerning 


Books.  With  Saturn  in  this  Scheme  you 
wYv  have  the  Globes  of  the  Earth  and 
Moon  drawn  in  their  true  proportion, 
to  put  you  in  mind  again  of  a  Thing 
worth  remembring,  viz.  how  very 
fmall  our  Habitation  is  when  compar’d 
with  that  Globe  or  the  Ring  about  it. 
And  now  any  one,  I  fuppofe,  can 
frame  to  himfelf  a  Pifture  of  the 
Night  in  Saturn,  with  two  Arches  of 
the  Ring,  and  five  Moons  fhining 
about,  and  adorning  him.  This  then 
is  what  I  had  to  fay  to  the  primary 
Planets. 

We  are  now  come  a  little  lower,  to 
make  an  enquiry  into  the  Attendants 
of  thefe  Planets,  efpecially  our  own. 
And  here  we  fhall  not  only  confider 
their  Aftronomy,  but  fhall  alfo  fearch 
into  their  Furniture  and  Ornament, 
if  they  are  found  to  have  any  fuch 
thing,  which  we  have  deferred  confi- 
dering  till  now.

Conjectures  than  any  of  the  other  re*  Books, 
mote  Planets.  But  it  is  quite  other- 
wife,  and  I  can  fcarce  find  any  thing 
to  fay  of  it,  becaufe  I  have  not  a  Pla¬ 
net  of  the  fame  Nature  before  my  Eyes, 
as  in  all  the  primary  ones  l  have.  For 
they  are  of  the  fame  kind  with  our 
Earth  •,  and  feeing  all  the  ACtions,  and 
every  thing  that  is  here,  we  may  make 
a  reafonable  Conjecture  at  what  we 
cannot  fee  in  thofe  Worlds.  \ 

But  this  we  may  venture  to  fay,  The 
without  fear,  that  all  the  Attendants  */ 
of  Jupiter  and  Saturn  are  of  the  fameSsa- 
Nature  with  our  Moon,  as  going  round turn  °f  ^ 
them,  and  being  carried  with  them;^ 
round  the  Sun  juft  as  the  Moon  is  with  our  Moon . 
the  Earth.  Their  Likenefs  reaches  to 
other  Things  too,  as  you’ll  fee  by  and 
by.  Therefore  whatfoever  we  can 
withreafon  affirm  or  conjecture  ofour 
Moon  (and  we  may  fay  a  little  of  it) 
muft  be  fuppos’d  with  very  little  Alte¬ 
ration  to  belong  to  the  Satellites  of  Ju¬ 
piter  and  Saturn ,  as  having  no  reafon 
to  be  at  all  inferior  to  that.

again  with  broad  Valleys.  For  in 
thofe  Parts  oppofite  to  the  Sun  you 
fnay  fee  the  Shadows  of  the  Moun¬ 
tains,  and  often  difcover  the  little 
round  V  alleys  between  them,  with  a 
Hillock  or  two  perhaps  rifing  out  of 
them.  Kjpler  from  the  exafit  round- 
nefs  of  them  would  prove  that  they 
are  fome  vaft  work  of  the  rational 
Inhabitants.  But  I  can’t  be  of  his 
mind,  both  for  their  incredible  Large- 
nefs,  and  that  they  might  eafily  be 
occafioned  by  natural  Caufes.  Nor 
can  I  find  any  thing  like  Sea  there, 
tho’  he  and  many  others  are  of  the  con¬ 
trary  Opinion  I  know.  For  thofe  vaft 
Countries  which  appear  darker  than 
the  other,  commonly  taken  for  and 
called  by  the  Names  of  Seas,  are  difco- 
ver’d  with  a  good  long  Telefcope,  to 
be  full  of  little  round  Cavities ;  whofe 
Shadow  falling  within  themfelves, 
makes  them  appear  of  that  Colour  : 
and  thofe  large  Champains  there  in  the 
Moon  you  will  find  not  to  be  always

upon  them :  neither  of  which  two  Books. 
Things  can  agree  to  the  Sea,  There-  ‘ 
fore  thole  Plains  in  her  that  leem 
brighter  than  the  other  Parts,  mu  ft 
confift,  I  fuppofe,  of  a  whiter  fort  of 
Matter  than  they.  Nor  do  I  believe 
that  there  are  any  Rivers,  for  if  there  mr  ?w 
were,  they  could  never  efcape  our^n* 
Sight,  efpecially  if  they  run  between 
the  Hills  as  ours  do.  Nor  have  they 
any  Clouds  to  furnifti  the  Rivers  with  Nor 
Water:  For  if  they  had,  we  fhould  c/r/Ws’ 
fometimes  fee  one  part  of  the  Moon 
darken’d  by  them,  and  fometimes 
another,  whereas  we  have  always  the 
fame  Profpedt  of  her. 

’Tis  certain  moreover,  that  the^^» 
Moon  has  no  Air  or  Atmofphere  {m^an^ateK 
rounding  it  as  we  have.  For  then  we 
could  never  fee  the  very  outermoft 
Rim  of  the  Moon  fo  exaftly  as  we  do, 
when  any  Star  goes  under  it,  but  its 
Light  would  terminate  in  a  gradual 
faint  Shade,  and  there  would  be  a  fort 
of  a  Down  as  it  were  about  it;  not  to 
mention  that  the  Vapours  of  our  At¬ 
mofphere  confift  of  Water,  and  con- 
fequently  that  where  there  are  no  Seas 

or 


es  concerning 


Books. or  Rivers,  there  can  be  no  Atmof- 
phere.  This  is  that  notable  difference 
between  the  Moon  and  us  that  hin¬ 
ders  all  probable  Conje&ures  about  it. 
If  we  could  but  once  be  fure  that  there 
were  Seas  and  Rivers  in  it,  it  would  be 
no  weak  Argument  to  prove  that  it  has 
alio  all  other  Furniture  which  belongs 
to  our  Earth,  and  the  Opinion  of  Xe¬ 
nophanes  might  be  true,  that  it  has  its 
Inhabitants,  Cities,  and  Mountains.

Plants  or  Animals,  whofe  whole  nou- 
rifhment  comes  from  liquid  Bodies, 
can  thrive  in  a  dry,  waterlefs,  parch’d 
Soil.

concerning  it,  becaufe  I  know  of  no¬ 
thing  like  them  to  found  a  Conjecture 
upon.  And  yet  kis  not  improbable 
that  thofe  great  and  noble  Bodies 
have  fomewhat  or  other  growing  and 
living  upon  them,  though  very  dif¬ 
ferent  from  what  we  fee  and  enjoy 
here.  Perhaps  their  Plants  and  Ani¬ 
mals  may  have  another  fort  of  Non- 
rifhment  there.  Perhaps  the  Moifture 
of  the  Earth  there  is  but  juft  fufficient 
to  caufe  a  Mift  or  Dew,  which  may 
be  very  fuitable  to  the  G  rowth  of  their 
Herbs.  This  I  remember  is  Plutarch9 s 
Opinion,  in  his  Dialogue  upon  this 
Subje£t.  For  in  our  Earth  a  very 
little  Water  drawn  from  the  Sea  into 
Dew,  and  falling  down  again  upon 
the  Herbs,  would  be  fufficient  for  all 
our  Needs,  without  any  Rain  or  Show¬ 
ers.  But  thefe  are  mere  Gueffes,  or 
rather  Doubts,  but  yet  they  are  the 
beft  we  can  make  oft  his,  and  all  thofe  Jupiter^ 
other  Moons :  for,  as  I  faid  before,  they 
are  all  of  the  fame  nature,  which  is  Moomturn 
proved  likewife  by  this,  that  as  our

l/Y\;but  of  one  Side  of  her,  fothey  turn  al¬ 
ways  the  fame  Face  to  their  primary 
Planets.  It  may  perhaps  feem  ftrange, 
how  we  fhould  come  to  know  this ;  but 
’tis  no  hard  matter,  after  that  Obfer- 
vation  which  I  juft  now  made,  that 
the  outermoft  of  Saturn's  Moons  can 
never  be  feen  but  when  fhe  is  on  the 
Weft- fide  of  her  Planet.  The  reafon 
of  which  is  plainly  this,  that  one  Side 
of  her  is  darker,  and  does  not  reflett 
the  Light  fo  much  as  the  other,  which 
when  it  is  turned  towards  us,  we  can¬ 
not  fee  by  reafon  of  its  weak  Light. 
This  always  happening  when  ’tis  Eaft 
of  him,  and  never  on  the  other  Side,  is 
a  manifeft  proof  that  fhe  always  keeps 
the  fame  Side  toward  Saturn.  Now 
fince  the  outermoft  of  Saturn’s  and  our 
Moon  carry  themfelves  thus  to  the 
Planets  round  which  they  move,  who 
can  well  doubt  it  of  all  the  reft  round 
Jupiter  and  Saturn  ?  And  there’s  a 
very  good  reafon  for  it,  namely,  that 
the  matter  of  which  thofe  Moons  con-

confequently  fly  with  a  greater  force

wife,  according  to  the  Laws  ofMotion, 
it  fhould  turn  the  fame  Side  always,  not 
to  its  Planets, but  to  the  fame  fix’d  Stars. 

This  Pofition  of  the  Moons,  in  re- 
fpeQ:  of  their  Planets,  muft  occafion  a 
great  many  very  furprizing  Appear¬ 
ances  to  their  Inhabitants,  if  they 
have  any,  which  is  very  doubtful, 
but  may  for  the  prefent  be  fuppos’d. 

An  enquiry  into  our  Moon  may  ferve 
for  all  the  reft.  Its  Globe  is  divided 
into  two  Parts,  in  fuch  a  manner,  that 
thofe  who  live  on  one  Side  never  lofe 
the  fight  of  us,  and  thofe  on  the  other  , 
never  enjoy  it.  Except  only  fomefew 
who  live  on  the  Confines  of  each  of 
thefe,  who  lofe  us,  and  fee  us  again  by 
turns.  The  Earth  to  them  muft  feem  TheAnr^ 
much  larger  than  the  Moon  doth  to  nomy  of 
us,  as  being  in  Diameter  above  four  ^  lnhaz 
times  bigger.  But  that  which  is  moft*  Mom 
furprizing,  is,  that  Night  and  Day 
they  fee  it  always  in  the  very  fame 
part  of  the  Heaven,  as  if  it  never 
moved  :  fome  of  them  as  if  ’twas  fal¬

all  its  Countries,  even  of  thofe  that  lie

the  Body  of  the  Moon.  But  the  Light 
that  they  receive  of  us  is  five  times 
larger  than  what  we  receive  from  them. 
So  that  in  dark  Nights  that  part  that 
hath  the  Advantage  of  being  towards 
us,  receives  a  very  glorious  Light  from 
us,  tho’  Kjpler  thought  otherwife* 
Their  Days  are  always  of  the  fame

Sun  riling  and  fetting  to  them  but  once 
in  one  of  our  Months,  makes  the  time 
both  of  their  Light  and  Darknefs  to  be 
equal  to  1 5  of  our  Days.  If  their  Bodies 
were  of  the  fame  Materials  with  ours,

ed  in  fuch  long  Days.  For  the  Sun  is  Books* 
not  farther  from  them  than  he  is  from 
us.  This  will  be  the  Cafe  of  thofe  that 
live  upon  the  Borders  of  the  two  He- 
mifpheres  we  mentioned  ^  but  thofe 
that  live  under  the  Poles  of  the  Moon

in  the  middle  of  their  Summer,  in  their 
Days  of  three  Months  length,  they  ve¬ 
ry  often  find  it  extreme  Cold.  I  call 
thofe  the  Poles  of  the  Moon,  round 
which  the  fix’d  Stars  feem  to  turn  to 
its  Inhabitants,  which  are  different 
from  ours,  and  alfo  from  thofe  of  the 
Ecliptick,  although  they  move  round 
thefe  latter,  at  the  diftance  of  five  De¬ 
grees,  in  a  period  of  nineteen  Years. 

Their  Year  they  count  by  the  Motion 
of  the  Stars,  and  their  return  to  the 
Sun,  and  kis  the  fame  with  ours. 

They  can  eafily  do  it,  becaufe  they 
have  the  Stars  Day  and  Night,  not- 
withftanding  the  Light  of  the  Sun  : 
for  they  have  no  Atmofphere  (which

their  Obfervations.  Nor  have  they 
any  Clouds  to  obftruft  their  View,  fo 
that  it  is  ealier  for  them  to  find  out 
the  Courfes  of  the  Planets,  but  more 
difficult  to  make  a  true  Syftem  of

Wrong  Foundation,  by  fuppofing  that 
their  Earth  Hands  Hill,  which  will  lead 
them  into  more  dangerous  Errors  than 
This  may  ever  it  did  us.  All  that  I  have  faid

satum.  The  Length  of  their  Day  and  Night  is 
always  equal  to  the  Time  of  their  Re¬ 
volution  :  For  example,  the  fifth  Moon 
moves  round  Saturn  in  80  Days,  and 
the  Days  and  Nights  there  are  equal  to 
Forty  of  ours.  Both  their  Summer 
and  Winter  (Saturn  moving  round  the 
Sun  in  thirty  Years)  are  fifteen  Years 
long.  Therefore  it  is  impoffible  but 
that  their  way  of  living  mult  be  very 
different  from  ours,  having  fuch  tedi¬ 
ous  Winters,  and  fuch  long  watching 
and  fleeping  times.

lefs  ground  for  a  Probability  in  him 
than  in  the  Moon.  For  we  are  not  yet

Roundnefsand  equal  diftribution  of  his

For  that  very  fmall  inequality  on  his 
Surface,  which  is  difcovered  by  the  Te-

which  makes  Men  fancy  they  fee  boil¬

Magnitude  being  efteem’d  to  be  about 
three  Minutes  Diameter  ;  and  Coper*

tur’d  co  fay  that  the  Magnus  Orbis  was 
but  a  Point  in  refpecf  of  the  Sphere  in

Confequence  that  every  one  of  them

is  certainly  their  own  :  for  it’s  impoffi-

they  reflect  it  at  fuch  a  vaft  Diftance, 
This  is  the  Opinion  that  commonly

there’s  no  Argument  for  it,  as  that  the 
Sun,  which  is  one  of  them,  cannot  be 
brought  to  this  Rule.  But  it’s  more 
likely  they  are  fcatterM  and  difpers’d

from  one  another,  as  the  neareft  of

Here  again  too  I  know  Kjfler  is  of 
another  Opinion  in  his  Epitome  of  Co~

lie  cannot  allow  that  they  have  as  large

Thoufand  or  two  of  them  with  our

cover  twenty  times  that  number.  But 
Kfpler  had  a  private  Deiign  in  making 
the  Sun  thus  fuperiour  to  all  the  other 
Stars,  and  planting  it  in  the  Middle  of 
the  World, attended  with  the  Planets: 
For  his  Aim  was  hereby  to  ftrengthen 
his  Cofmographical  Myftery,  that  the 
Diftances  of  the  Planets  from  the  Sun 
are  in  a  certain  proportion  to  the  Dia¬ 
meters  of  the  Spheres  that  are  infcri- 
bed  within,  and  circumfcribed  about 
Euclid'3  s  Regular  Bodies.  Which 
could  never  be  fo  much  as  probable, 
except  there  were  but  one  Chorus  of 
Planets  moving  round  the  Sun,  and 
fo  the  Sun  were  the  only  one  of  his 
kind. 

But  that  whole  Myftery  is  nothing 
'  but  an  idle  Dream  taken  from  Pytha¬ 
goras  or  Plata7 s  Philofophy.  And  the 
Author  himfelf  acknowledges  that  the 
Proportions  do  not  agree  fo  well  as 
they  fhould,  and  is  fain  to  invent  two 

or

or  three  very  filly  Excufes  for  it.  And  Books® 
he  ufes  yet  poorer  Arguments  to  prove  virv 
that  the  Univerfe  is  of  a  fpherical  Fi¬ 
gure,  and  that  the  Number  of  the  Stars 
mult  necelTarily  be  finite,  becaufe  the 
Magnitude  of  each  of  them  is  fo.  But 
what  is  worft  of  all  is,  that  he  fettles 
the  Space  between  the  Sun  and  the 
Concavity  of  the  Sphere  of  the  fix’d 
Stars,  to  be  fix  hundred  thoufand  of 
the  Earth’s  Diameters.  For  this  rea- 
fon,  which  he  has  no  Foundation  for, 
that  as  the  Diameter  of  the  Sun  is  to 
that  of  the  Orbit  of  Saturn ,  which  he 
makes  to  be  as  i  to  2000,  fo  is  this  Dia¬ 
meter  to  that  of  the  Sphere  of  the  fix¬ 
ed  Stars®  I  cannot  but  wonder  how

ingenious  a  Man,  and  fo  great  an  A-

Opinion  with  all  the  greateft  Philofo-

fame  Nature  with  the  fix’d  Stars.  And 
this  will  give  us  a  greater  Idea  of  the 
World,  than  all  thofe  other  Opinions* 

For  then  why  may  not  every  one  ofT^  stars

yvw  there’s  a  manifeft  reafon  why  they

placed  at  an  equal  distance  from  the 
Sun  and  fix’d  Stars  ;  we  fhould  then 
perceive  no  difference  between  them. 
For,  as  for  all  the  Planets  that  we  now 
fee  attend  the  Sun,  we  fhould  not  have 
the  leaft  glimpfe  of  them,  either 
becaufe  their  Light  would  be  too 
weak  to  affect  us5  or  that  all  the  Orbs 
in  which  they  move  would  make  up 
one  lucid  Point  with  the  Sun.  fn  this 
Station  we  fhould  have  no  occafion  to 
imagine  any  difference  between  the 
Stars,  and  fhould  make  no  doubt  if  we 
had  but  the  Sight,  and  knew  the  Na¬ 
ture  of  one  of  them,  to  make  that  the 
Standard  of  all  the  reft.  We  are  then 
plac’d  near  one  of  them,  namely,  our 
Sun,  and  fo  near  as  to  difcover  fix  other 
Globes  moving  round  him,  fome  of

that  we  would  in  that  cafe  \  and  con¬

very  much  from  one  another  in  Clear-

will  not  in  the  leaft  have  altered  their 
diftance*  Thofe  that  have  hitherto

ble  Probability  in  fo  difficult  a  Cafe,  I 
fhall  here  make  ufe  of.  Seeing  then 
that  the  Stars,  as  I  faid  before,  are  fo 
many  Suns,  if  we  do  but  fuppofe  one 
of  them  equal  to  ours,  it  will  follow 
that  its  diltance  from  us  is  as  much 
greater  than  that  of  the  Sun,  as  its  ap¬

pofe  I  clos'd  one  End  of  my  twelve-

the  Middle  of  which  I  made  a  Hole  not 
exceeding  the  twelfth  Part  of  a  Line* 
that  is  the  hundred  and  forty  fourth 
Part  of  an  inch.  That  End  I  turn’d 
to  the  Sun,  placing  my  Eye  at  the

that  I  had  made  ufe  of  in  my  Microf- 
copes,  of  much  about  the  fame  Dia¬ 
meter  with  the  former  Hole.  Then 
looking  again  towards  the  Sun  (taking 
care  that  no  Light  might  come  near 
my  Eye  to  hinder  my  Gbfervation)  I 
found  it  appeared  of  much  the  fame 
Clearnefs  with  Sirius .  But  calling  up 
my  account,  according  to  the  Rules  of 
Diopt ricks ,  I  found  his  Diameter  now 
was  but  tf  2  part  of  that  hundred  and 
eighty  fecond  part  of  his  whole  Dia¬ 
meter  that  i  faw  through  the  former 
Hole.  Multiplying  ,1,  and  t{-2  into 
one  another,  the  Produd  I  found  to 
be  2  76V*.  The  Sun  therefore  being 
contracted  into  fuch  a  Compafs,  or  be¬ 
ing  removed  fo  far  from  us  (for  it’s  the

his  diftahee  then  from  us  will  be  to 
his  prefent  diftance  undoubtedly  as 
27664  is  to  1  5  and  his  Diameter  lit¬ 
tle  above  four  Thirds,  4  '.  Seeing

then  Sirius  is  fuppofed  equal  to  the  Books®

likewife  4^  ar*d  that  his  Diftance  to 
the  Diftance  of  the  Sun  from  us  is  as 
27664  to  1.  And  what  an  incredible 
Diftance  that  is,  will  appear  by  the 
fame  way  of  reafoning  that  we  ufed  in 
meafuring  that  of  the  Sun.  For  if 
25  Years  are  required  for  a  Bullet  out 
of  a  Cannon,  with  its  utmoft  Swift- 
nefs,  to  travel  from  the  Sun  to  us ; 
then  by  multiplying  the  Number 
27664  into  25,  we  (hall  find  that  fuch 
a  Bullet  would  fpendalmoft  feven  hun¬ 
dred  thoufand  Years  in  its  Journey  be¬ 
tween  us  and  the  neareft  of  the  fix’d 
Stars.  And  yet  when  in  a  clear  Night 
we  look  upon  them,  we  cannot  think 
them  above  fome  few  Miles  over  our 
Heads.  What  I  have  here  enquir’d 
into,  is  concerning  the  neareft  of  them.

placed  in  the  vaft  Spaces  of  Heaven, 
as  to  be  as  remote  from  thefe  as  thefe

if  we  confider  the  infinite  Power  of

twenty  or  thirty  Figures  only,  in  our 
decuple  Progreffion,  but  of  as  many 
as  there  are  Grains  of  Sand  upon  the

even  this  Number  exceeds  that  of  the 
Fix’d  Stars?  Some  of  the  Ancients,  and 
Jordanw  Brunm  carry’d  it  further,  in

hindrance  to  fuch  a  Motion.  Then 
the  whole  Matter  moving  round  at 
once,  upon  the  Axis  as  it  were  of  a 
Cylinder,  did  not  a  little  puzzle  him 
in  giving  Reafons  for  the  Roundnefs 
of  the  Sun  :  which  however  they  may 
fatisfy  fpme  People  that  do  not  confider 
them,  really  prove  nothing  of  the 
Matter.  In  this  sethereal  Matter  the 
Planetsfloat,  and  are  carried  round  by 
its  Motion :  and  the  thing  that  keeps 
them  in  their  own  Orbs  is,  that  they 
themfelves,  and  the  Matter  in  which 
they  fwim,  equally  ftrive  to  fly  off 
from  the  Center  of  this  Motion.  A-

Cartes3

Cartes ,  the  firft  Man  that  ever  began  Book 2* 
to  talk  reafonably  of  that  Matter,  v-OTw' 
fhould  never  meddle  with,  or  light 
on  it.  Plutarch  in  his  Book  of  the 
Moon  above-mentioned  fays5  that 
fome  of  the  Ancients  were  of  Opinion, 
that  the  Reafon  of  the  Moon’s  keep¬ 
ing  her  Orbit  was,  that  the  Force  of 
her  Circular  Motion  was  exactly  equal 
to  her  Gravity,  the  one  of  which 
pull’d  her  to,  as  much  as  the  other 
forc’d  off  from  the  Centre.  And  in 
our  Age  Alphonfus  Borelhs ,  who  was 
of  this  fame  Opinion  in  the  other  Pla¬ 
nets  as  well  as  the  Moon,  makes  the 
Gravitation  of  the  primary  Planets  to 
be  towards  the  Sun,  as  that  of  the 
Secondary  is  towards  the  Planets 
round  which  they  move  :  Which 
Sir  Jfaac  Newton  has  more  fully  ex» 
plain’d,  with  a  great  deal  of  Pains 
and  Subtilty  ;  and  how  from  that 
Caufe  proceeds  the  Ellipticity  of  the

of  its  being  deftroyed  by  inch  an  irre¬ 
gular  Motion,  becaufe  the  iEther 
round  it,  which  is  at  reft,  keeps  the 
Parts  of  it  from  flying  out.  With  the 
Help  of  fuch  a  Vortex  a's  this  I  have 
undertook  in  that  Effay  to  explain 
the  Gravity  of  Bodies  on  this  Earth, 
and  all  the  Effefts  of  it.  And  I  fup- 
pofe  there  may  be  the  fame  Caufe 
as  well  of  the  Gravitation  of  the 
Planets,  and  of  our  Earth  among  the 
reft,  towards  the  Sun,  as  of  their 
Roundnefs  :  A  Thing  fo  very  hard 
to  give  an  Account  [of  in  Cartes1  s

I  mull  differ  from  him  too  in  the 
Bignds  of  the  Vortices,  for  I  cannot 
allow  them  to  be  fo  large  as  he  would 
make  them.  I  would  have  them  dil- 
perfed  all  about  the  immenfe  Space, 
like  fo  many  little  Whirl- pools  of  Wa¬ 
ter,  that  one  makes  by  the  ftirring  of
